When our eldest son reached puberty he began showing all the signs and symptoms of a 'typical' of the change and came to us in frustration not liking what was going on. After some research we purchased the Michael's brand. We just told him we were 'upgrading' his multi-vitamin and said nothing more. After a couple of weeks I asked how he was doing and he said, "Mom, I feel like myself again!" The blend in this multi-vit is fantastic. We have not fought with acne or emotional swings that usually come with the teen years. That's more than any parent could ask for!
